Alabama Senate candidate Roy Moore sparked a wave of backlash on Sunday when he referred to Native Americans and Asians as "reds and yellows" during a campaign speech.

Roy Moore is set to face Luther Strange -- who has received President Trump's endorsement -- in a primary runoff next week, and the race is expected to be incredibly close. Moore, a former chief justice on Alabama's state Supreme Court, sparked backlash on Sunday when he used racially insensitive terms during a campaign speech.

“We were torn apart in the Civil War — brother against brother, North against South, party against party. What changed?” Moore said. "“Now we have blacks and whites fighting, reds and yellows fighting, Democrats and Republicans fighting, men and women fighting."
